Microsoft closes down Word Flow for iOS, encourages users to get SwiftKey instead
Word Flow keyboard app for iOS was a product of Microsoft's Garage project. I say “was” because Microsoft decided to pull the plug on the development and remove Word Flow from the App Store.
According to a message posted on the app's page on Microsoft Garage, the development of Word Flow was an experiment that it's now complete (whatever that's supposed to mean). Moreover, the developers recommend those who used Word Flow on their iOS devices to go ahead and download SwiftKey instead.
If you're yet aware, Microsoft had already bought SwiftKey last year, so it's quite understandable that the Redmond-based company would recommend one of its apps to replace Word Flow.
Also, having two apps that do almost the same thing doesn't make sense, which is probably the reason Word Flow was removed from the App Store today.
